I want to build the 8x8 matrix using WS2811 LED strip
I will cut it into 8led strips
My question is about the best way to connect it.
I will be powering it from external 5v power supply. I have 2A would this be enough to power 64 leds plus arduino.
I am plannint to connect this external power supply to gnd and vin pin of arduino. And also to the 5v and GND of the first 8led strip. and then with cable chain connect the other 7 8 led strips.
Would that work or do I have to connect 5v and ground to first strip and chain connect e.g next 3 strips and then continue with data wire to remaining 4 strips but connect those 4 strips directly to exernal 5v just like I did with first four.
Not sure If I am making myself clear so I drew two diagrams.
Also I have some doubts i 5v is enough to power arduino Nano via VIN pin. I thought it is 6v-12v required.
Do I need any resistors or capacitors
